I finally managed to fly my quad pretty stable when hovering after a long patience. It flies for about 10-12min with a 3300mah 4s 25C battery.
I am running Arducopter 3.0.1 rc7. when I tried to run for the first time, the compass which was working before did not work! it did not let me arm because of fail in pre-arm checks due to this compass sensor.
it shows that compass(internal) is bad( which before was not and also I didn't crash!).
so what I did was, I turned off the pre-arm checks and the compass and magnetometer. I am not using gps ( its just installed on the quad). I always fly in stab mode and I didn't try any other.
So the question begins with-
1) why is the internal compass not being detected?
2) what tuning parameter should I change to keep it on a certain level at a particular throttle value?
- when I fly it goes up, then after3-4 seconds keep descending itself.
3) compass and magnetometer are not required in stabilize mode, right?
